A tension resistance device is coupled to a second location within the structure. The tension resistance device generates a first force when a tension force is applied thereto and generates a lesser second force when the tension force is not applied thereto. The second end of the line is coupled to the tension resistance device wherein the first force is applied to the line when it is in tension and the second force is applied to the line when it is not in tension. The line traverses at least one Z-shaped path within and in a plane of the structure. The line is coupled to the structure at each inflection point of the Z-shaped path(s) for supporting movement of the line there along. ## Claims ### Claim 1 A dynamics management system for a structure, comprising: a line exhibiting rigidity in tension and flexibility in compression, said line including a first end and a second end, said first end configured to be coupled to a first location within the structure, said line traversing at least one Z-shaped path within the structure wherein said at least one Z-shaped path lies in a plane, each said Z-shaped path having a plurality of inflection points defined there along;
